60 wpc out of a "typical" multi-channel amp is surely not enough power for HT, especially in a room that large and speakers that are not highly efficient.
As to using in-wall speakers, the performance will be far inferior to individual speakers in their own cabinets. This has to do with diffraction, baffle size, etc... resulting in poor soundstage and imaging, speaker localization, etc...
You are setting yourself up for a lot of disappointment and future upgrades. That is, unless you are only looking for a minimum of performance i.e. something that "works" while being "convenient" and very simple. Given the amount of labor to install multiple in-walls, i would think very seriously prior to going this route. Your local dealer / installer may tell you something different, but we have nothing to gain by sharing this info with you. Be careful how you spend your money and what you take for granted. It is FAR cheaper and easier to "think big" in the preliminary stages than to have to upgrade / change / re-arrange later. Sean
